Dynamic resolution rules joy

In the following code, what do you believe the output should be?

class Program
{
    static void Main(string[] args)
    {
        dynamic stupid = new Stupid{Age = 3};

        Console.WriteLine(stupid.Age);
    }
}

public class Stupid : DynamicObject
{
    public int Age { get; set; }

    public override bool TryGetMember(GetMemberBinder binder, out object result)
    {
        result = 1;
        return true;
    }
}

Argh!

The default is to use the actual type members, and then fall back to the dynamic behavior. Whereas I would expect it to first check the dynamic behavior and then fall back to the actual members if it can’t find dynamic stuff.

Quite annoying.
